Git ShellSpec Definition

This is a work-in-progress. It is an attempt to comprehensively define the git command in ShellSpec. I'm doing this exercise mostly in order to suss out edge cases in ShellSpec and to help refine it's specification to ensure it's usefulness and viability.

Initial definition to include:

[x] config [x] help [x] init [x] clone [x] add [x] status [x] diff [x] commit [x] branch [x] checkout [x] merge [x] log [x] rev-list [x] rev-parse [ ] stash [ ] tag [ ] fetch [ ] pull [ ] push [ ] remote [ ] apply [ ] cherry-pick [ ] rebase [ ] revert [ ] blame [ ] grep
